The short version

What changed, and why it matters

This commit is a large code cleanup and refactoring of the wallet connection feature in the Keystone 3 firmware. It removes many duplicated Rust modules and C functions that generated QR-code sync data for specific wallets (Aptos, Solana, Sui, XBull, Keystone companion app, etc.) and replaces them with a single generic function. It also fixes some memory leaks by adding SRAM_FREE calls and removes unused/commented-out code. There is no direct evidence in the commit of a security vulnerability being fixed; it appears to be a maintenance refactor.

Recommended action

Treat as routine maintenance. Review the new unified UR generation paths for correct handling of master fingerprint length and path parsing, and verify the added SRAM_FREE calls cover all allocation sites. No urgent security action is indicated by this commit alone.
